The Discussion on “Sankejiuzhi” by “Gongyang” Scholars in the Qing Dynasty

He Xiu and Song Zhong were scholars in Han Dynasty and Three Kingdoms Period who summarized "Sankejiuzhi" in "Gongyang" studies, which is the most important issue in "Gongyang" school and the most important area that "Gongyang" scholars cannot but research in the following dynasties. Kong Guangsen re-established the "Sankejiuzhi" , which embodied the thought of Wan school. Liu Fenglu claimed that he believed the doctrine of He Xiu, but mixed it with the thoughts of other schools. Chen Li introduced different "Sankejiuzhi" theories, but had the same overall idea with He Xiu and did not deviate from his notes. From these statements, it can be concluded that "Gongyang" school in Qing Dynasty doesn't follow a linear development of Changzhou school, but pursues a multiple model of development.
